which statement about the following equation is true?\n3x² - 8x + 5 = 5x²\nthe discriminant is less than 0, so there are two real roots.\nthe discriminant is greater than 0, so there are two real roots.\nthe discriminant is less than 0, so there are two complex roots.\nthe discriminant is greater than 0, so there are two complex roots.
Answer
Explanation:
Step1: Rewrite the equation in standard form
First, rewrite (3x^{2}-8x + 5=5x^{2}) as (ax^{2}+bx + c = 0). Subtract (3x^{2}) from both sides: (0=5x^{2}-3x^{2}+8x - 5), so (2x^{2}+8x - 5=0). Here (a = 2), (b = 8), (c=-5).
Step2: Calculate the discriminant
The discriminant formula is (\Delta=b^{2}-4ac). Substitute (a = 2), (b = 8), (c=-5) into the formula: (\Delta=(8)^{2}-4\times2\times(-5)). [ \begin{align*} \Delta&=64+40\ \Delta&=104 \end{align*} ] Since (\Delta = 104>0), when (\Delta>0), the quadratic equation (ax^{2}+bx + c = 0) has two distinct real roots.
Answer:
The discriminant is greater than 0, so there are two real roots.
